Step-by-step explanation:
We need to apply the following identity:
Then, applying this, you know that for 
:
We need to remember that:
and 
Therefore, we need to substitute these values into .

Answer:
30
Step-by-step explanation:
x=6
4 by 6 =24
24 + 6 =30
I’m not sure but good luck with your test
Answer:
x=17°
Step-by-step explanation:
163+x=180 (L.P)
x=180-163
x=17°
As shown in the given figure
line a // line b ⇒ given
MR and NP are transversals
So, for ΔMOP and ΔRON , we can conclude the following
(1) ∠1 = ∠2 ⇒⇒⇒ alternative angles are congruent
(2) ∠ MOP = ∠ RON ⇒⇒⇒ vertical angles are congruent
(3) ∠ 4 = ∠ 3 ⇒⇒⇒ alternative angles are congruent
So, from 1,2 and 3
∴ ΔMOP <span>~ </span>ΔRON by AAA-Rule
